thanks everybody for the great info.. I will for sure start saving I mean I would love to make my own so I know if something does go wrong I know exactly what to fix and I think that is what I will do is make my own..... would a ve-200 t-stat work good for one? hannahlou you said you made that out of a wine cooler where did you find that? or did you already have it..... thank you everybody and sorry it took me so long to reply back for some reason my phone never notified me that someone had commented I had to go to my latest started threads and find out myself.
